To all wibo/lt t ntwy concer-n,.-

in the accompanying drawings, in which- Figure A1 is an elevation of my improved device. Fig. 2 is a similar view of one of the additional scales. Fig.l 3l is a sectionin the Fig. 4 is a section in the line 4 4 of F ig. I, and Fig. 5 is a perspective view of a modified form of eXpansible scale. Referring to the drawings, A is a suitable frame, preferably rectangular in form and of the same general proportions as-the base Qf Secured within this frame isa ilat plate of wood, metal, pasteboard, or the like B. In front of the plate B is asheet C of any desired material,-

preferably of paper, Celluloid, or a similar substance, but possibly of sheet metal `or another material of the same kind. At one side of this sheet C is a scaleD, regularly subdivided from top to bottom, and opposite this scale D is a series of numerals E, marking the various subdivisions of the scale. Above and below the v-scale l) areslots d,

.through which extends a iexblev endless y band E, composed of material o'f'two different colors, preferably having secured to it on that portion of its` length at vthe back of the plate B a handle e. vice illustrated in the drawings the band' is composed of a red lower and a white upper portion joined at e". The indicator, formed by t e junction of the two' colors, is accentuated by a pointer e2.

vas possible the appearance of a thermometer, a wafer F covers the-lower slot d? and thisrwafer corresponds in color to the lower portion of theband, so that the band appears ike. a column of colored liquor'rising from the bulb of a thermometer.

My device is intended primarily for v'use in' Sunday-schoolsfand the like, where a high attendance is sought and some Vsuitable and,`

conspicuous record of the attendance is deslred. With my device -it is-veryeasy by merelysettingthe joining-point of the two For instance, in the de-y 'Io simulate as muchA l parts of the band opposite the proper ligure to indicate ,exactly the attendance in a graphic and conspicuous manner. I find that bythe use of such a device great interest is` aroused among the attendants of the Sunday-school, for in practice the same is reset eachweek and the children are very anxious to have it rise rather than 'fallf Inthis way'the children are given aninterest in the size of the school andput forth unusual efforts to lincrease the attendance.

It will be obvious that when the attendance at the school reaches the top of the scale some a paratus other than an entirely new one sliiould be devised to accomodate the growing needs, yand for this purpose I provide slots g` above and below the line of numerals E, and

throughtliese slots I pass the ends of a supplemental scale G, which is one of a series of supplemental scales furnished with the device. It will be `obvious that in changing from one scale to another if one began Where` the other ended constant confusion would `arise if the attendance were not `reasonably regular, for in such a case continual shifting of the'scales would be necessary, which would destroy the effectiveness vrof the device as a gra hic representation.,v I therefore make'v t ough the slots g, and 'in this case the sup plemental'scales .are added to the original one, running, however, in numerical rogres-` sion from 0 to the` highest num er. In .this instance ,the average attendance may be shown midway between the ends of the scale jvregardless of its amount by merely moving the endless bandto bring the average attendance ap roximately midway between. the ends of t e sheet. It will be seen that whatever the figures upon the numeral-scales may.` bethe unitsare substantially the same in size and correspond to thesproper markings on the scale D beneath the moving band or ribbon.
